"ذهنی که یک بار روشن شده باشد نمی‌تواند دوباره تاریک شود"

Once your mind has been opened to new ideas and knowledge, you can't just unlearn it or go back to a state of ignorance. Think about it like this: once you've seen the world in color, you can't just forget that and see it in black and white again.

This idea traces back to the Age of Enlightenment in the 17th and 18th centuries, a time when thinkers like John Locke and Voltaire were all about pushing the boundaries of knowledge and understanding. They believed that once people were exposed to new ways of thinking, society could only move forward. There was no going back.

Here's a practical example: imagine you're learning to ride a bike. In the beginning, it's tough. You fall, you scrape your knees, and you wobble all over the place. But once you figure it out, you can't really forget how to ride a bike. That knowledge sticks with you, even if you don't ride for years. The same goes for your mind when it learns something transformative.

So, how can you use this wisdom? Keep seeking knowledge. Read, explore, question what you know. When you challenge your mind and expose yourself to new ideas, you're growing in ways that can't be undone. If you’re stuck in a rut, it might be because you’ve stopped learning. Shake things up. Take a class, talk to someone with a different perspective, or travel somewhere new. The more you expose yourself to new experiences and information, the more enlightened you'll become.

Now, let’s bring this idea to life with a story. Picture a guy named Tom. Tom's always lived in a small town, never really ventured out. He’s content but feels like something’s missing. One day, he decides to take a trip to a big city. He’s hit with a sensory overload - the skyscrapers, the hustle and bustle, the sheer diversity of people and cultures. He tries new foods, goes to museums, and talks to people with life experiences totally different from his own.

When Tom goes back to his small town, he's different. He's seen and learned things he can't unsee or unlearn. Maybe he’s more tolerant of different viewpoints now, or perhaps he’s developed a craving for more adventure. He can’t go back to the way he was before - his mind has been opened, and it's a one-way street.

You see, once we experience or learn something transformative, it changes us. And that’s okay. In fact, it’s amazing. It’s what makes us grow as individuals. So, don’t be afraid of seeking out those mind-opening experiences. They’re what keep life vibrant and fulfilling. Sometimes it's uncomfortable at first, but that discomfort is just a sign that you're pushing your boundaries.

In essence, the light of knowledge and experience can't be dimmed. So, keep that light shining bright. It's one of the most human things we can do.
